摘要：

Poly(vinylidene fluoride-hexafluoropropylene) (PVdF-HFP) gel electrolytes comprising a combination of plasticizers, ethylene carbonate (EC) and propylene carbonate (PC) and lithium salt LiX (X = BF4-, CF3SO3-, ClO4-) have been prepared using the solution casting technique in an argon atmosphere. The prepared electrolytes were subjected to ionic conductivity, compatibility with lithium metal anode and thermogravimetric (TG)/differential thermal analysis (DTA). The membranes, which possess lithium salt, LiBF4 exhibited maximum conductivity and on contrary it undergoes severe passivation with lithium metal. All these membranes are found to be stable thermally about 70degreesC. (C) 2004 Elsevier Ltd. All rights reserved.
